My daughter is 2.5 months old. She is around 12 pounds. Long with skinny legs. She is also a he at wetter most of the time. I have a variety of newborn diapers but don't hold enough pee and are tall enough in the rise. So I think I need a one size diaper. Need one that can fit small babies with tiny legs and hold a ton of pee. Is there anything out there like that?

Night time I am having some of the same issue. She had been wearing sandy's xs fitteds but they aren't tall enough in the rise and she leaked out of it the other morning (soaks it every night) and this is with 1-2 doublers. Is there anything else I can try that will fit a little bigger and hold her?

Also interested for some velcro options for the grandparents. Good velcro. And inserts or doublers that are good but small to fit smaller diapers. Maybe even something stay dry but with natural fibers.

I have a long skinny guy and we moved to the OS Simplex around that weight. They come in snaps or split and the aplix is pretty good. The soaker has a stay dry option and there's a pocket for extra absorbency. Maybe a hemp doubler like this with a narrow cut like Hemp Babies Diaper Doublers or GMD hemp doublers (they may also have a stay dry option).

Maybe try a small Sandy's. I think the Motherease website gives a comparison of the number of ounces each size holds. Or look into a tried and true night diaper like the Sustainablebabyish snap less multi or sized bamboo fleece night diapers. I was using small Sandy's with two inserts, then large Sandy's and it was getting really bulky. Switched to the snap less multi and I use the two inserts plus a hemp insert under Wool and no leaks. Try Disana soakers or interlock.

My ds was/is shaped like that and a heavy wetter too. It kind of threw me for a loop with cloth diapers for a bit because of it. I'm a lover of cotton, but the answer for us has been bamboo. It's more absorbent than cotton and a lot less bulky, which was the exact combo we needed. Sweet Iris flats, Applecheeks bamboo trifolds, Lalabye Baby diapers, & Grovia pfs are all working great for us. The Applecheeks are the least absorbent of all those and I don't like their pockets on ds, but I love the trifold inserts for daytime stuffed in a Kawaii Pure & Natural pocket which has fit ds so well since he was tiny. I love the Sweet Iris flats padfolded into Grovia or Flip covers. Super easy, so soft, very trim and bulletproof. Washes and dries nice and quickly too. Lalabye Baby are great too, price isn't bad but they seem like nice quality and work great even overnight. I've only had the Grovia pfs a short time but am liking them so far. They are our bulkiest bamboo option but so soft and absorbent. They hold a lot more than a cotton pf of the same size.
